I've had my mobile number for 12 years (the cell companies here are all just as bad)!
One Friday evening I started getting calls asking, "Have I won the house?" - Some radio station was having a competition, and 1st prize was a brand new house! The competition line was just one digit off my number!
After telling the first 15 that they had dialled the wrong number, I got tired of repeating my self, and decided to have some fun!
The next punter phoned and asked if she had won the house?
I said 'YES - CONGRATULATIONS!!! Come to our offices on Monday morning and collect your prize!"
And I told the same thing to the next 10 callers!
The Radio Station changed the competition number the next weekend ...
